AI Can Detect Emergence From Coma Better Than Doctors

Recovery from severe traumatic brain injury (TBI) can be frustrating for families and trauma professionals alike. It occurs in fits and starts, and the longest wait occurs while waiting for the patient to wake up. We perform serial neurologic exams and monitor closely for any visible response to commands.

A group of medical and engineering researchers at SUNY Stony Brook theorized that muscle movements in response to commands might be too subtle for human detection during early emergence from coma. They developed an AI system called SeeMe that studied the patients’ facial appearance down to the level of pores, and trained it to detect very fine motor movements in response to three commands:

  • Stick out your tongue
  • Open your eyes
  • Show me a smile

A group of 16 normal volunteers and 37 TBI patients were then tested while being video recorded. Both SeeMe and trained experts judged responses.

Here are the factoids:

  • SeeMe detected facial responses 4 days earlier than the trained experts
  • It detected eye opening in 86% vs 74% of human observers
  • SeeMe was able to detect mouth movements in 94% of patients without endotracheal tubes
  • The SeeMe-detected responses correlated with the clinical outcome at discharge

Bottom line: Severely brain-injured patients are able to respond to commands with subtle facial muscle movements before human observers can detect them. A specially trained AI like SeeMe can identify these movements and help predict recovery sooner than clinicians. Imagine being able to tell the family, who has been seeing their loved one making no progress, that improvement is occurring! And imagine what other applications focused AI can have on other clinical areas where human senses don’t have the capacity that carefully trained machines do!

Utility Of The Hybrid OR For Trauma: Recent Literature

As I mentioned in the last post, the early literature on the use of the hybrid OR for trauma patients was just so-so. However, additional work has been done, and the real benefits are becoming clearer. Today, I’ll describe a pair of more recent, related papers that examined trauma outcomes in the hybrid OR.

The research was performed at the University of Florida Health, Gainesville. The group published an initial paper analyzing 106 adult trauma patients managed in a regular OR, comparing them with another 186 who were taken to a newly repurposed hybrid OR. This room was a remodeled angiography suite that was located within the OR complex.

Here are the factoids:

  • Overall demographics of the two groups were similar
  • Initial hemoglobin in the hybrid group was about 1g/dL lower (10.2 vs 11.1)
  • Nine times as many hybrid patients had a REBOA balloon placed (9% vs 1%)
  • The time to hemorrhage control was significantly shorter in the hybrid group
  • The hybrid OR patients required fewer blood and plasma transfusions between 4 and 24 hours after arrival
  • Infectious complications and ventilator days were significantly lower in the hybrid OR group
  • Mortality was similar (13% hybrid vs 10% conventional)

The authors published a follow-up paper three years later in which they analyzed the original data to determine the cost-utility and value. They did this by examining the clinical outcomes relative to the cost of this new resource. They found that the costs across the patient admission were similar in the hybrid and conventional groups ($55K vs $51K).  The authors concluded that the better outcomes described in their first paper came with no significant increase in cost.

Bottom line: There is still precious little data on the benefits of the hybrid OR for trauma patients. Even though the total numbers appear to be small, it is difficult to amass the hybrid group sizes described here. It is the best US data we have so far, and shows promising results for minimal extra cost.

In my next post, I’ll conclude with some tips and tricks for setting up your own hybrid room.

The Electronic Trauma Flow Sheet: Oops! Now What Are My Options? Part 2

In the last post, I discussed what to do if your hospital is thinking about switching to an electronic trauma flow sheet (eTFS). Today I’ll give you some tips on what to do if the cat’s already out of the bag and it’s already been implemented.

The number one priority is to show the impact of the eTFS on the trauma program. This involves the same two components I’ve already written about:

  1. Accuracy. The trauma program must measure the impact of the “garbage in” phenomenon on the performance improvement (PI) process. This is critically important, because bad data will decrease the quality of your PI analysis. For example, if the PI program is not able to determine that hypotensive patients are being taken to CT scan, patient harms could occur that are not detected. This could result in two bad things for your trauma program (and patients): unanticipated mortality, and deficiencies during a verification visit.
    Be on the lookout for extraneous or impossible data points. Keep a list of information that is consistently missing. Use all of this information to work with your hospital administration to find ways to make it better.
  2. Efficiency.  Your program must also find a way to measure the efficiency of abstraction by the trauma program manager, PI coordinator, registrars, or whoever is tasked with doing it. Keep track of the time needed to abstract a trauma activation chart vs a non-activation. This will give you an idea of the extra time needed to process the eTFS data. Or just clock in when starting eTFS abstraction, and clock out when finished. The amount of time will probably astonish you.
    Monitor average days to completion of registry entries, and look at the number of cases not fully abstracted by 60 days to see if there is a noticeable impact on your registry concurrency. Delays here are common in centers with high volumes of trauma activations because the abstractors must spend an inordinate amount of time trying to pull information from the eTFS.

Once your hospital has taken the plunge and adopted the eTFS, it is very difficult to go back. Many centers are convinced that “this next update is going to make it so much better.” It never does! I have visited programs that have been tweaking their processes and reports for almost 8 years! None have been able to improve it significantly.

Your hospital administration will ultimately need to decide how to proceed, depending on how damaging the eTFS is to the trauma PI program and how much it will cost to continue to tweak it vs returning to a paper flow sheet. Good luck!

The Electronic Trauma Flow Sheet: Oops! Now What Are My Options? Part 1

I’ve spent several posts showing you the major problems inherent in using an electronic trauma flow sheet (eTFS). It boils down to Garbage In / Garbage Out and time.  It costs a lot of money and weakens an otherwise robust trauma performance improvement process.

Here’s the real bottom line:

” A hospital using an electronic trauma flow sheet is paying a lot of money for a product that forces them to pay even more money for people to essentially transcribe inaccurate data back onto a paper trauma flow sheet.”

So what can be done about it? That depends on whether the eTFS has already been implemented. Today, I’ll discuss what to do if it’s still in the planning stages.

You’ve just heard that your hospital is considering switching to an eTFS. Here’s what you should do:

  1. Warn everyone you can, loudly! Use all of the ammunition you’ve read about here. Talk to your administrative contacts. Ultimately, your CEO needs to hear the concerns.
  2. Visit another hospital with similar trauma volumes using the same eTFS. Don’t just call them up and ask how it’s going. Go and visit, and watch during an actual trauma activation. How is the scribe doing? Can they keep up? Is there a “cheat sheet?” Then talk to the people who abstract the eTFS data. Ask how long it takes compared to the old days of paper.
  3. Consider a test implementation, and have two scribes, one using the eTFS and one using a paper sheet. After each trauma activation, objectively compare scribe performance, accuracy, and completeness. The eTFS cannot be allowed until they are equivalent (which I have never seen).
  4. During the test implementation, have two abstractors analyze the data, one using the eTFS and one using the paper sheet. How long does it take to find all pertinent demographics, sign-in times, primary survey, secondary survey/exam, procedures, vital signs flow, fluids & IVs, I&O? Was the patient hypotensive? What activities occurred during those times: procedures, drugs, CT scans? The eTFS cannot be allowed until they are equivalent (which I have also never seen).
  5. Continue to work with your hospital administration, showing them this data. Hopefully, they will see the light and abandon this “great idea.” At least until the technology improves, which it hasn’t for the last ten years!

But what if they don’t? Or what if you’ve walked into a program already using it? I’ll talk about that in the next post on Friday.

The Electronic Trauma Flow Sheet: What Does(n’t) Work – Part 2

In my last post, I wrote about how the electronic trauma flow sheet (eTFS) practically assures a garbage in situation. Today, I’ll dig into what happens on the back end, and how it also creates a garbage out situation.

There are two ways to view the eTFS on the back end (abstraction phase): read a paper report (timeline), or view it live in the electronic health record (EHR). Let’s look at each:

  • Paper report. Anyone who has actually generated one of these can tell you that it’s a disaster! Reams of paper, typically 20-30 pages. Hundreds of “chronological” entries. Inclusion of extraneous information from later in the hospital stay. Ebola screens. Sepsis score. Many things that have nothing to do with trauam. They are difficult to understand, and it is very difficult to pick out the true “signal” due to all the “noise!” And it doesn’t matter how customized the report is, it will nearly always fail on these issues.
  • Live EHR. Your abstractor (registrar, PI coordinator, trauma program manager) logs in and pulls up the screen(s) containing the eTFS. Once again, they need to mouse and keyboard around, looking for the specific things they are interested in. Piece by piece, they try to assemble a human-understandable picture of what happened. But since it’s not chronological across all activities in this view, it can be very challenging.
  • Both. And then there’s the issue of Garbage In I discussed yesterday. Conflicting patient arrival times. Lack of accurate team arrival documentation. Vital signs and IV infusions are recorded after patient expiration or discharge. No massive transfusion start time. Inaccurate data from the scribe’s “cheat sheet.”

The final result of all of the shortcomings listed above is this: it increases trauma flow sheet abstraction time by three-fold or more! If you are a trauma center with a two-tier trauma activation system, you probably have a lot of TTAs. Therefore, it takes a lot of time to abstract all those flow sheets. Which ultimately means that you (this really means your hospital) will have to pay for more registrars / PI coordinators / nurses!

Hopefully, I’ve convinced you that the eTFS is not a great way to go. In the next post, I’ll discuss strategies to use if your hospital is “considering” moving to an eTFS. And next week, I’ll wrap up with what to do if you’ve already been burdened with it.
